Bottom line: For marketers, MarkLayer is a free annotation layer for landing pages, competitor sites, ad creatives, and dashboards. Pin hypotheses, suggest copy edits, and run teardowns directly on the live page. No PDF screenshots, no sign-up for stakeholders.
Marketing teams iterate on landing pages, run competitive teardowns, and review live campaigns with stakeholders who don't live in Figma or Notion. MarkLayer turns any URL into a markup canvas: pin comments on a competitor's headline, suggest edits to a hero CTA on staging, or annotate analytics dashboards with hypotheses for the next test. Share the link; stakeholders see the annotated page in any browser.
The problem
Marketing review cycles fragment fast: landing page mockups in Figma, copy in a Google Doc, competitive teardowns in Slack screenshots, dashboard insights in another deck. By the time anyone reads the feedback, the page has changed and the comments are decoupled from what they referenced.

How it works
1. Open the page. Open the landing page, competitor site, or campaign URL you want to review.
2. Activate MarkLayer. Click the extension icon to start annotating.
3. Mark up hypotheses. Pin CRO hypotheses to the hero, comment on copy choices, draw arrows at friction points in the funnel.
4. Bundle related pages. Use multi-page projects for full-funnel reviews: landing → pricing → checkout in one shareable link.
5. Share with the team. Drop the link in Slack or your project tool. Stakeholders open it without signing up and reply in context.
Frequently asked questions
Can I annotate competitor sites with MarkLayer?
Yes. MarkLayer works on any webpage, including competitor sites, third-party tools, and SaaS products you do not own. The annotations are private until you share the link.
Is this useful for CRO and A/B test planning?
Yes. Many marketing teams use MarkLayer to pin test hypotheses to specific page elements, then revisit the annotated page after the test to see whether the hypothesis held up.
Does MarkLayer work for ad landing page review?
Yes. It works on any URL, including ad-specific landing pages, paid social destinations, and PPC pages on staging.
How is this different from Userback or BugHerd for marketing teams?
Userback and BugHerd are paid platforms with workflow tooling around feedback. MarkLayer is the free, annotation-only option. Pair with whatever PM/tracker tool you already use.
